how is it that heavier objects don’t fall faster (e.g. Pisa experiment) , but heavier people go faster downhill on skis or sleds than less heavy people

Answer 1

Heavier objects fall faster through air and friction. While the acceleration of gravity is the same, the resistance to motion is effectively less.

A 180lbs force pulling a person down from gravity will get them moving faster and faster until 180lbs of drag and friction are resisting them. If you did this with a 120lbs person, you need less drag/friction to resist them and so a lower top speed.
